VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 324,271, dated August 11, 1885.

Application filed March 10, 1885.

To all whom it may concern.-

Be it known that I, WILLIAM H. PAYNE, a citizen of the United States, and a resident of Camden, New Jersey, have invented a new and useful Improvement in Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, making part hereof.

The nauture of my invention will fully appear from the following description and claims.

In the drawings, Figure 1 is a vertical lon gitudinal sectional view of my device; Fig. 2, a detached side view of the cap of the ventilator; Fig. 3, a perspective view of the internal deflector; Fig. 4, a similar view of the base, also showing the pipe or flue to be ventilated.

A is a pipe-flue or conductor upon which my ventilator is set; E, a base-cup or concave disk set around the upper end or" flue A, through which the flue projects; 0, an internal double cone or deflector shielding the up per end of the fine or pipe A; D, an inverted concave disk held above the deflector G by means of the arms or supports E. E are similar arms or supports to hold the deflector O in place.

I construct my ventilator of sheet metal or cast-iron, preferably the former. WVhen made of sheet metal, I strike upthe various concave disks, each of one piece, in a manner similar to the plan employed to stamp up ordinary tin basins, and I form the deflector O by uniting two such disks by their flaring edges. This deflector is open above and below, as shown, and envelopes or shields the top of the flue. The opening below is much larger than the diameter of the flue, and permits a draft to pass up around the flue, and into and through the deflector.

F F are holes or openings in the disk 13, to permit the drip or exit of water which may be caught in the said disk. Supposing the air-current to be from right to left, as shown in the drawings, the air will take a course through the ventilator, (indicated by the arr0ws,) thus inducing an upward draft through the flue. The concave disks B, and the two concave disks forming the double cone 0, and

(No model.)

the inverted concave disk D are each made of one piece of stamped-up metal in the manner or mode employed in stamping up the ordinary tin or sheet-metal wash-basin; but the intermediate double cone, 0, is open above and below. This construction presents no corners or angles, but every turn or deflection is a curve, which adds to the strength and appearance of my device, as well as facilitates the draft orpassage of air-currents.

It will be observed that I call my disks conical in shape. \Vhile this exact form may be used, I in practice only approximate that form, approximating sufficiently thereto to give the proper deflection or direction to the air-currents, and I desire the words conical and cone in my claims to have this broad significance.

What I claim as new is 1. In a ventilator, the combination of the concave lower disk, B, inverted concave upper disk, D, and the double internal conical deflector, O, surrounding the internally-projecting flue or pipe A, arranged and operating substantially as described.

2. I11 a ventilator, the combination of the concave lower disk, 13, provided with openings F F, inverted concave upper disk, D, and a double internal conical deflector, 0, surrounding the internally-projecting flue or pipe A, all arranged and operating substantially as described. 3. In aventilator, the combination of the vertically-opposite concave disks l3 and D, the concave surfaces of which face each other, separated, as shown, and the intermediate double conical deflector or shield G, open above and below, the upper open end of which the upper cone, 1), and the lower opening 01' :uneter of llue A as to leave a free air-space which is below the plane of the upper pearound the flue at its point of entry into the riphery 01 the disk 13, and the flue A, passing deflector C, substantial] y as described. upward closely through lower disk, B, and \VILLTAM 1L PAYNE. freely into the lower part of the double conical deflector (l, the lower opening in which is so much larger in diameter than the outer di- Witnesses:
